Joan Miró's Bon cop...de lluna is a striking example of the artist's mature work, characterized by both the black outlines and the thick applications of black ink. The dynamism of the present work—where moon and stars are set against a blank background with ink spatter reminiscent of the abstract expressionists—fully captures the energy and boldness that Miró embraced in the last decade of his life. On June 18, 1978, in an interview with Santiago Amón, discussing recent works on canvas Miró stated, "I painted these paintings in a frenzy, with real violence, so people will know that I'm alive, that I'm breathing, that I still have a few more places to go. I'm heading in a new direction" (Margit Rowell, ed., Joan Miró: Selected Writings and Interviews, Boston, 1986, p. 301).

While the new directions and boldness of his late works are clearly visible in the present composition, one also finds Miró's traditional pictorial lexicon of signs and symbols. Stars, moon, woman, bird and sun all formed a poetic language that he implemented throughout his lifetime. Margit Rowell expands on the driving force behind Miró's work: "What was important to Miró was the immediacy of his images, that they be impulsive, corrosive, eruptive, emptied of conventional meanings or allusions and purified to a primordial presence" (Margit Rowell, ed., 1986, ibid., p. 10). His interest in primitive art as well as the art theory and anthropology based around this art in the 1920s and 1930s contributed to his pictorial language.
